what does 11 more than the first mean
The second angle of a triangle is more than the first . The third third is fifteen less than six times the first. find the angles
The statement is incomplete: "second angle of a triangle is more than the first." However, taking into account
the heading of the problem, that statement must be "second angle of a triangle is 11 more than the first."
Angle one, a: x
Angle two, b: x + 11
Angle three, c: 6x - 15
a + b + c = 180
x + (x + 11) + (6x - 15) = 180
x + x + 11 + 6x - 15 = 180
8x - 4 = 180
8x = 184
x = 23
x + 11 = 34
6x - 15 = 123
23 + 34 + 123 = 180
The first angle is 23 degrees.
The second angle is 34 degrees.
The third angle is 123 degrees.
